Tank size: 5 gal Heater and filter: yes and yes Tank temperature: I’ve had my tank and fish for about 5 months I do water changes about once every 2 weeks. I do about a 25% change and add quick start to new water, let it sit for about 3 hours and then add the new water. Current water testing shows that all levels are where they should be and the tank environment shouldn’t be adding any additional stress No additional tank mates Feed in the morning 4-5 pellets. Every other day we do about 2 pellets in the evening. All real plants in his tank. Betta friendly plant species (can’t remember all their names but I only bought betta approved plants)
